    Thomvest is a $300mm cross-stage venture capital fund based in Silicon Valley and Toronto. The firm invests the capital of one individual, Peter Thomson, whose family owns the majority of Thomson Reuters. Peter started Thomvest in 1996 and has invested in more than 50 private companies since that time. The firm primarily invests across three areas: financial and real estate technology, cybersecurity and cloud infrastructure, and sales and marketing technology. The company typically makes initial investments of $500,000 to $20 million, and has resources to follow up those investments as needed.
